I have a simple code that I'm trying to wrok into my website to clear a textbox with a default value, when a user click on it, the default value should clear out so that the user can enter his/her value. Here is what I have but I'm not sure if its correct since its not working. I just started on JQuery
$(document).ready(function()
{
$('#startDateBox').click(function()
{
if(('#startDateBox')=='Beginning')
{
$('#startDateBox').val('');
}
})
});
You're wrong in this part:
if(('#startDateBox')=='Beginning')
First, you missing $
. Second, I think you want compare the startDateBox
value, then use val()
.
Try this:
$(document).ready(function()
{
$('#startDateBox').click(function()
{
if($('#startDateBox').val()=='Beginning')
{
$('#startDateBox').val('');
}
})
});
You missed the first .val()
, and the $
in front of the ('#startDateBox')
on the same line. You could also use $(this)
to reference the textbox, as within that function this
refers to the textbox DOM element itself. Wrapping it with the jQuery function $()
gives you access to all the framework's goodies.
$(document).ready(function()
{
$('#startDateBox').click(function(){
if($(this).val() == 'Beginning')
^^^^^^ Here
{
$(this).val('');
}
})
});
I would suggest for HTML5 browsers use this
<input type="text" id="Beginning" placeholder="Beginning" />
if($('#startDateBox').val() =='Beginning')
this is the line that needs to be changed
also
$('#startDateBox').on("focus", function()
{
// code here
the click will not handle hitting tab until that text box is focused
Well, if(('#startDateBox')=='Beginning')
will always be false...
I think you meant something more like:
if($('#startDateBox').val() == 'Beginning')
I wrote a very small jquery plugin for this purpose recently:

$('#input').placeholder("Placeholder Text");
if($('#input').val() === $('#input').placeholder()){ return false; }
